On their own, the BT620s work with mobiles but the A320s add PC audio streaming from your laptop. The lack of labels on the right and left earpiece buttons makes initial operation tricky but charging and pairing were largely hassle-free.
We had big hopes for the BT620s, which feel light, look good, have pretty lights and good headset breeding. But we were greeted by bad news. The sound quality is mediocre both with our test V3x mobile and the stereo dongle. The main offence was given by weak bass and an unimpressive sound that was quick to distort at volume.
What a disappointment for such a pretty little thing.
